Use of kmdb to Stop the Live
Operating System

The use of kmdb to stop the live operating system
using mdb -K or by setting a breakpoint in the live operating
system is intended for use by developers and not on production systems. When
the operating system kernel is stopped by kmdb, operating
system services and networking are not executing, and other systems on the
network that depend upon the target system will not be able to contact the
target system.
